If you are not allergic to dairy, try this frosting on the Easy Pumpkin Spice Cake. I got the recipe from allrecipes.com. It was really good together!

Note: This frosting is gluten-free (if you use gluten-free vanilla) but the cake I am recommending to put it on is not. So, if you have a gluten allergy, use this frosting on your favorite gluten-free cake.
